Patented Sept. 2, .1 S) 1 2%.

To all whom (it new concern,

lie it known that I, Maniacs Pnrrano, a citizen of the United States,a1d a resident of Newark, :lflssex county, New Jersey, have inventedcertain new and useful improvements in inding:Machines, (Qase L3,), ofwhich the following is a speclt sation.

My invention relates to wind ng machines for winding cops, of that k ndn which relative reciprocation is produced hetween a thread guide and awinding spindle, and the successive advances of the thread are p,r,dnced byitriction roller means to. which rotary motion is imparted atinter- 'vals by the winding spindle.

The invention relates particularly to that type of such machines whichwind cops on paper tubes, the cops having tapered ends and a cylindricalbody. The rear end (it such :1 C0}? iS known as the heel. The throw ofthe thread due to the reciprocation off the thread guide is known as thetraverse, and a complete traverse may be regarded as being composed Ofan out stroke and a back stroke,

The object of the invention is to provide a friction roller which isnormally at a distance from the windin spindle, and which, l. ,etweentraverses, during the building of the heel, moved toward the windingspindle so. as to be rotated thereby, thus producing the advances, forforming the reel of the cop.

A further object is to move the friction r-oller diminishing distancestoward the spindle on the successive back strokes during the building ofthe heel.

Another object is to provide means for causing the ft'riction roller toapproach the winding s indle on the early ba t okes, which means ismounted on a statimiary part, such as the frame oi" the machine, orindependently of the rec procating parts, and is adapted to be contactedby a suitable contact n e nl'icr reciprocating with said parts. 'i A-iarticnlarobject of the invention is to provide active heel shapingmechanism, which is mounted independently of the reciprocating parts andactuated by the back strokes thereof to move the friction roller towardthe spindle so as to be rotated thereby.

A. further objectis to simplify and improve the construction andarrangement of the several parts.

\Vith these and other objects in view, the invention consists in theconstructions, arrangements and combinations hereinafter described,illustrated by the preferred emlmdiments in the accompanying drawings,and more particularly pointed out in the appended claims.

In the said drawings: Figure 1 is an end elevation of the machine; Fig.2 is a sectional front elevation showing the mechanism for swinging thetraverse bar; Fig, 3 is a plan view of the parts in front of the :lrameoi, the machine, showing the heel of the cop partially coinplctcd andthe traverse bar, Friction roller and thread guide at the end of the outstroke; Fig. 4- is a similar view, but showing the reciprocating partsat the end of their back stroke, with the traverse bar and frictionroller swung toward the spindle and the roller contacting with thethread of the cop; Fig. 5 is a similar view, showing the heel completedand the flriction roller working on the partially completed body of thecop. The parts are shown at the end oi the back stroke. l n dotted linesare indicated the completed cop and the friction roller at the end ofits final back stroke. Fig. (i is a sectional detail, showing the springactuated incomplete nut for coupling the friction roller to the threadedtraverse bar; l ig. T is a detail sectional view showing the fork oryoke for coupling the friction roller with the thread guide; and

.ll lg. 8 a detail plan view of the universal joint connection betweenthe rear end oi the traverse bar and the oscillating arm forreciprocating the same,

In these drawings, the nluncral ll indicates any suitable :lorm, o'lframe, which in practice is considerably larger than is indicated in thedrawings. On the frame is mounted a driving shaft 12. This shaft 12rotates a plurality of spindles 13, projecting forward through theframe; but only one spindle is illustrated in the drawings. The shaft 12may drive the spindle 13 by means of a bevel friction disk 15 and abevel friction gear ill; but it is obvious that such details areimmaterial.

The numeral 17 indicates a suitable form oi, thread g 'lide, betweenwhich and the spindle 13, a relative recipmcation is probuilding cop.

duced. It is regarded as preferable to reciprocate the thread guide; andthe means for effecting such reciprocation may be varied widely. In theillustrated construction, a cam-shaft 18 (driven in any suitable mannerby the driving shaft 12 or otherwise) is provided with a cam 19, whichoscillates a spring-supported lever 20, which in turn oscillates arock-shaft 21, being con-- nected with an arm 22 thereof by a link 23.An arm 24 carried by the rock shaft is com nected to a traverse bar 25and reciprocates the same. In accordance with the best form of theinvention, the reciprocation of the traverse bar is imparted to thethread guide in the following manner: A friction roller 26 is mounted onthe traverse bar; and this roller is shown as being provided with acollar extension 27 which is engaged by a coupling or fork 28, whichfork is secured adjustably to a reciprocating rod 29 on which the threadguide 17 is adjust-ably mounted.

According to the best form of the invention, the thread guide is mountedindependently of the traverse bar 25. To this; end it is shown mountedon the rod 29, which itself is mounted for longitudinal rectilin-.

ear reciprocation, as by being received in stationary bearings 30 on theframe. Thus,

by virtue of the coupling 28, the thread guide partakes of thereciprocation of the traverse bar 25, but said bar moves laterallyindependently of the thread guide, in the manner hereinafter described.

The roller 26 gives the successive advances to the thread guide 17 forthe the is heel of the produced by building of This advance cop.screwthreaded means through the rotation of,

the friction roller at intervals by the winding spindle, through contactof the pe-,

riphery of the roller with the thread of the ment of the inventionillustrated, the traverse bar 25 is threaded, and the friction roller 26is adapted to be coupled with they threads thereof; so that rotation ofthe roller on the traverse bar advances the roller along the bar.Through suitable connections, such as already described, the rollerimparts this advance to the thread guide 17.

The roller 26 is provided with a form of quick release device, which isadapted to travel with the roller and has movement relative thereto forengagement and disengage- In the particular embodi- Suitable means areprovided for shaping the heel of the cop, which means may be widelyvaried. In accordance with this fea ture of the invention, the traversebar 25 and the friction roller 26 are laterally yieldable for thepurpose of enabling the friction roller to be brought into frictionalcontact with the thread of the cop at the conclusion of each back strokeduring the building of the heel of the cop. In the best form of theinvention, the traverse bar is swiveled at its rear end for thispurpose; being connected by universal joint connection with the arm 24.Such joint may be of various forms. As shown, the upper end of the arm24 is provided with spaced ears 36, concave on their inner faces andhaving transverse slots 37, in which are received a pivot pin 38 securedto the ball end of the traverse bar 25. The bar is, thus, enabled toswing sidewisetoward and from the spindle 13.

The fork 28 is swiveled, as indicated at 39, so as to cause no bindingwhen the traverse bar 25 and the friction roller 26 are swung toward thespindle.

In accordance with the form of the invention illustrated, mechanism ismounted inde pendently of the reciprocating parts and is actuatedthereby to move the traverse bar and roller laterally between traverses.In the best construction, a bell-crank lever has a long pivot portion 40mounted in a suitable stationary support or bracket 41; and one arm 42of this lever is disposed in the path of an abutment or contact member43 mounted adjustably on the shaft 29 of the thread guide. The other arm44 of said lever is connected by a link 45 with a projection 46 on aswinging bracket 47. Said bracket 47 is pivotally supported as indicatedat 48, and affords a bearing through which the traverse bar 25 slides.As will be apparent, when, the abutment 43 pushes the arm 42, which ispreferably inclined forward, to the rear, the traverse bar 25'and theroller 26 are moved toward the spindle 13. 7V hen the contact member 43again moves forward, the traverse bar and the roller, and likewise thelever 42, are restored to their former positions by a spring 49, whichdraws the bracket 47 against an adjustable stop 50. Instead of theabutment 43, moving contact means may be provided'in any suitablemanner, as, for example, the fork 28 may be caused to contact with thearm 42 of the hellcrank' lever.

In the operation of the invention, at the conclusions of the backstrokes of the thread Lose distributing means during the building of theheel of the cop, the lever 42 is actuated and causes the friction roller26 to approach the spindle 13 and thus be rotated by frictionalengagement with the thread of the building cop. This rotation advancesthe roller and he thread guide, and also the abutment 4L8. Consequently,on each successive back stroke, during the building of the heel of thecop, the abutment 43 moves the lever a shorter distance, and the roller,consequently, approaches a less distance toward the spindle as the copbuilds up in thickness. Finally, the abutment no longer contacts withthe lever; and thereafter the roller is not advanced toward the spindle,but has rectilinear movement only. The roller 26 now proceeds to buildup the cylindrical body of the cop; for this purpose, contacting on eachback stroke with the high part of the cop and producing the requisiteadvance. In the preferred form of the invention illustrated, the roller26 is in the nature of a thin disk, whose width is materially less thanthe traverse of the thread (indicated by the letter Z) in the drawing),and the thread guide 17 is located substantially opposite the center orhigh point of the periphery oil. the disk, said periphery being slightlyinclined and rounded. By adjusting the stop 50, the width of the cop maybe varied,

\Vhile the machine is shown as operating on a tapering spindle and coptube, it operates as well on cylindrical spindles and tubes.
